In this scientific work are analysed two types of natural risk analysis paradigm: behavioural and structural, according to state's socio-economic level of development. It was ascertain that in developed countries, the natural hazard is approached through behavioural paradigm, of materialist origin, and in the under developed countries, the approach is done through structural paradigm, on account of human vulnerability causes of illegal distribution of resources and social inequality, with implication in poverty increasing and limiting individual and group skills for coping crisis situations.
